Sodium Monitor Model 8036

Sodium Monitor Model 8036

Product catalog summary

Overview: The Sodium Monitor Model 8036 is designed for power station applications, offering a wide measuring range from 0.01μgkg–1 to 10mgkg–1. It features full sample temperature compensation, a 'pumpless' liquid handling section for low maintenance, automatic range changing, and a simple calibration sequence controlled by a microprocessor.

Key Features:

Measuring Range: Covers 0.01μgkg–1 to 10mgkg–1, suitable for various power station applications.
Temperature Compensation: Ensures accurate measurements by compensating for sample temperature variations.
Low Maintenance: The 'pumpless' design reduces maintenance needs.
Automatic Range Changing: Automatically adjusts the current output to cover two decades.
Calibration: Simple, microprocessor-controlled sequence with automatic adjustments.

Applications:

Water Treatment Plant: Early indication of resin exhaustion and treated water quality.
Condensate Monitoring: Detects small condenser leaks by monitoring sodium levels.
Saturated Steam in Drum Boilers: Monitors sodium to detect carryover and deposition issues.
Once-through Boilers: Ensures water/steam purity by monitoring sodium post-condensate polishing plant.

Technical Specifications:

Accuracy: ±10% of concentration or ±0.02μgkg–1, whichever is greater.
Reproducibility: ±5% of concentration at constant temperature.
Response Time: Less than 4 minutes for 90% step change from 1 to 100μgkg–1.
Outputs: Two isolated current outputs (0 to 10, 0 to 20, or 4 to 20mA).
Calibration: Manual initiation with automatic sequence, frequency 1 to 4 weeks.

Installation Information:

Sample Temperature: 5° to 55°C.
Sample Flow: 50 to 500 ml/minute.
Sample Pressure: Minimum 0.14 bar (2 psig).
Ambient Temperature: 0° to 55°C.
Dimensions: Sensor unit: 300mm x 400mm x 200mm; Transmitter unit: 300mm x 300mm x 200mm.

Maintenance: Calibration is required every 1 to 4 weeks, reagent solutions need changing every 2 to 4 weeks, and monitor tubing should be replaced annually.

Compliance and Safety: The device conforms to EMC Directive 89/336/EEC and is marked with CE for electrical safety (IEC348). Proper installation in metallic conduit is essential to maintain performance.

Sodium Monitor Model 8036 > SS/8036_5 The prevention of damage to the boilers on modern powerstations becomes more and more critical as the cost of repairsand out of service plant continually rises. To reduce the effect ofboiler tube corrosion and the formation of scale on the inside of the tubes, the levels of impurities in the various parts of thesteam/water cycle must be carefully monitored.Sodium ions are normally the most abundant species in solutionfound in boiler plant, therefore the measurement of sodiumprovides a valuable indication of the overall purity of the solution.Whilst on-line...

Heat exchanger this is used to bring the standard solution close to the temperatureof the sample during calibration. Thermal differences therefore are minimised and calibration times reduced. Pressure relief valve ֖ during a calibration sequence the sample flow to the constanthead unit is stopped. The valve releases the pressure to prevent pressurising the sample line. Solenoid valve > under the control of the microprocessor the valve is used to switchbetween sample in normal running mode and standard solution during a calibration sequence.
